I have a Canadian Dime 10 cents 2009 Can you tell me, if it is a DD double die please I just find this is really difficult some time to identify Diane
For machine doubling, the step and riser should be at 90 degree angles to one another. The face of the die cuts into the device. It can't possibly be curved.
I'm saying that the curved lines in the upper-left drawing are not indicative of machine doubling. The cut should be squared off. I've been trying to explain this to everyone for 10+ years. Why do you think machine doubling is referred to as "flat and shelf-like"?
Flat and shelf-like does not necessarily mean 90 degree angles to me. The horizontal part of the strike and the vertical part of the strike are at 90 degrees to each other in the drawing. Do you have a better drawing or explanation?
1) draw a horizontal line 2) draw a vertical line at a 90 degree angle to it 3) draw a curve at the intersection of the two lines 4) erase the 90 degree angle and voila, you have two flat lines at 90 degrees to each other connected by a curve.
It's a single squeeze era coin, the chart makes more sense for double squeeze era coins. Someone may have put it on their website, so some may follow that route that all such are worth something, but not for me. There is doubling, but MD comes the closest. Sorry Jim
I always looked at those lines not so much as curved but as 'drag' or 'stretch marks' as it were, showing how the metal has been 'moved'.
I can usually tell that too, but this one has me puzzled. I said nothing at all about a flat curve. Here is what I said: "Flat and shelf-like does not necessarily mean 90 degree angles to me. The horizontal part of the strike and the vertical part of the strike are at 90 degrees to each other in the drawing. Do you have a better drawing or explanation?"
Ahhh, let's just drop it. I don't have the tools to create the drawings any more. My AutoCADD is no longer on my computer. Still friends?
